Can the manual gear start in second gear? What are the consequences of starting in second gear?

Tell a joke. 10 years ago, when I first got my driver's license, I turned on the manual gear, stopped the engine halfway, and then restarted it. At that time, all the gears were turned off, which made me sweat. Later, when I saw the gear, I hung it in the second gear, but I always started with the method of 1 gear, that is, I only moved forward by loosening the clutch without refueling. No wonder it was turned off.

When I was learning to drive in a driving school, the coach made it clear that I could only start in 1 gear, and I was not allowed to start in 2 gears. Later, I drove myself in the same way. Basically, I started in the second gear. Until one taxi was boring and I watched the driver master drive, I actually found that the driver always started in the second gear.

I asked master, won't it be a problem for you to start in second gear? The driver said everything was wrong. I always start like this, saving time and speeding up. This taxi has traveled 654.38 million kilometers without any problems. It's just that the clutch plate has been replaced, which is normal wear and tear, and there is nothing wrong with the car.

Later, when I was driving by myself, I started in second gear slowly, mainly in the following situations:

1, downhill section starts.

As long as you put the brake on the downhill section, the car will move forward regardless of whether there is a gear or not, and it doesn't need much torque to start, so it is easy to start. It is easier to speed up when starting in second gear, of course, it depends on the situation. If you follow the car on the downhill section, you don't need much speed, but you can still start with 1 block, which is flexible to use.

2. Start when the road is slippery in rainy and snowy weather.

When the rain and snow weather starts, the road surface is slippery and the wheels are easy to slip. Usually start in second gear. The second gear torque ratio 1 gear is small, and the output power of the car is not large. Compared with 1 gear, the wheels are not easy to slip, and the second gear ratio 1 gear is good when starting on wet roads.

3. Start on the flat ground occasionally.

If you start on a flat ground, you will occasionally start in second gear, or you can start in 1 gear. Yes, it depends on your personal habits. Sometimes you need to speed up quickly and start from the second gear. If you are not in a hurry, start from the 1 gear.

It should be noted that 1 gear start and second gear start have different oil distribution and different driving behaviors. When starting from the second gear, the stop time in the semi-clutch is longer than 1 gear, and the strength of the fuel filler door is larger than 1 gear.

The difference between 1 gear and 2nd gear is the torque. Engine power = torque × speed, and the torque of 1 gear is almost twice that of the second gear, so 1 gear is suitable for uphill sections and sections requiring high power output, and the second gear is suitable for downhill sections and sections requiring no high power output.

So the second gear can start, but compared with 1 gear, the second gear has some characteristics:

1 and the second gear start is easier to stall than 1.

For manual gear, there is a matching problem between speed and gear. The speed corresponding to the second gear is 5 ~ 20km/h, and the starting torque is twice as small as that of 1 gear, so it is necessary to increase the throttle to match the starting process.

Once your throttle and clutch are not well matched, the power generated by the car is not enough to overcome the resistance and gravity, and it is easy to stall. For novices, it is easier to turn off the fire, and novices do not recommend starting in second gear. After getting familiar with the technical practice, let's talk about starting from the second gear.

The wear of clutch plates in 2nd gear and 2nd gear is greater than 1 gear.

When starting from the second gear, due to the small torque, in the process of releasing the clutch, it is generally necessary to stay in the semi-clutch position for a little longer than 1 gear, which is actually 1~2 seconds, or even shorter, and at the same time, it is necessary to cooperate with refueling. As we all know, the wear of the clutch plate is the biggest in the semi-clutch state, especially in the refueling door state.

The average life of ordinary clutch plates is about 65438+100000 km, which depends entirely on individual driving skills. Some people can use 15000 km, while others can only use 80000 km. According to experience, the second gear starting ratio 1 gear starting will aggravate the clutch disc wear by about 10%.

In other words, the clutch plates that people start with 1 every day can last for 10 years, while the clutch plates that you start with 2 gears every day can only last for 9 years. The time may not be accurate, but it means something like this. The start mentioned here includes not only the start when the car is cold, but also the start after temporary parking, such as starting before the traffic lights and driving normally, starting at least a dozen times a day.

The starting fuel consumption ratio of gear 3 and gear 2 is higher than that of 1 gear.

When starting in second gear, the throttle is obviously larger than 1 gear. Except uphill, 1 gear can start without stepping on the accelerator, but the second gear will generally step on the accelerator, and the intensity of stepping on the accelerator depends on the actual situation. Then you will see the engine speed soaring, but the speed can't increase quickly, which takes time.

After starting, in order to match the speed and gear, you have to continue to step on the accelerator deeply. In the whole process, the engine oil needs to last for a certain period of time to be reflected in the power, and the output power of the engine also needs time. In fact, a lot of oil was wasted during this period, because it could not generate forward momentum and was consumed in vain.

According to experience, generally speaking, starting in the second gear consumes 1 0 ~ 20% more gasoline than starting in the second gear, which is one of the reasons why some people drive too high. For the same car, some people drive 10L/ 100 km, while others may drive 8L/ 100 km because of different driving skills.

Don't say that second gear has started. As long as the technology is good, the third gear can start. The trick is to pedal hard. As long as you step on the accelerator hard enough, the clutch will not stall no matter how fast it is released, but this operation is not normal.

I've seen old drivers start in the second gear on an uphill road, almost stepping on the accelerator to the end, and the car moves like a catapult. This is to use the large throttle to quickly improve the power and loosen the clutch at the same time. However, this method is not advocated, and those who like to drive manual gears only play occasionally, because it consumes too much fuel and is not good for cars.

Therefore, as long as you can accept the shortcomings of starting in second gear, it is no problem for you to start in second gear. This car won't break down. Nothing more than using more oil, the clutch plate will wear faster. However, I suggest that it is better to start with 1 gear, which is still the first choice for most people. After all, the car was designed in 1 gear. If it is not used for starting, so much the better.
